SPECIFICATION forming part. of Letters Patent I fO. 862,999, dated May 17. 1887- t (No modrLl To all whom, it mr/y concern:

Bcit known that we, HENRY B. Rinu m and llIANNlNd F. lla'reunn, citizens of the United States, residing at Philadelphia, in the county if Philadelphia and State of Pennsylvania, rave invented a certain new and useful I|n rovement in Marble-hlolding Machines, of 'hich the following is a full, clear, and exact escription.

This invention relates to that class of stone ressing machines which have for their object 1c working ofslabs of stone into useful shapes hich are more or less ornamental.

The invention consists in a cutter and a caragc therefor constructed and arranged. to

aerate substantially 'as hereinafter particuvarly set forth and claimed.

In the accompanying drawings, in the seval figures of which like parts are similarly csignated, Figure 1 is a side elevation of a I ortiou of the movable head carrying the cuter-driving spindle, the cutter, and its carriage. Fig. 2 is a top plan view in the plane of the lowermost surface of the movable head. Fig. 3 is an end view of the cutter and its earriage. Figs. 4-, 5, and 6 are details of the cutter, and Fig. 7 is a side elevation of a modification of the operatingmechanism of the cutter-carriage.

The head a, which carries the cutter-d ri ving spindle b, may be arranged in any suitable frame, and is movable therein in any usual manner to adjust the cutter vertically to the height of the stone being worked. To the under side of the head a is secured horizontally in any suitable manner-as by a bolt, c--- a guideway, (7, made as a segment of a circle, and having a dovetail groove, 0, on its under side, as shown more particularly at A, to the right of Fig. 2.

fis a carriage provided with a bearing, 9, journaled to the lower end of the spindle Z), so as to rotate in a horizontal plane upon said spindle. This carriage has a flat surface and lateral projections h therefrom, which lit against the lower grooved side of the segment (I, so as to be capable of movcnent horizontally against said segment, the said fiat bed and projections being preferabl curved to the arcof the segment. The carrier f connected erations.

screws in any usual manner. In these journalboxes of the carriage is secured a horizontal shaft, Z, which receives between the journal boxes the cutter m. This cutter consists of a headaz,havinglongitudinal peripheral notches or sockets o, in which are fitted the tool-bladcs 1), (see details Figs. 5 and 6,) these blades be ing shaped for molding, sawing, and other op The blades are clamped in the head 21 by washers 1], arranged at each end of said head on the shaft Z, and a nut or nuts, 1', the washers being undercut on the facenest ad acent the cutlcnhcad, as indicated in Fig. '4.

The lower end of the spindle I) is provided with a beveled pinion, s, which meshes with a bowled pinion, I, on the shaft 1, and said spindle, being driven at its other end in any usual manner, imparts rotary motion to the shaft Z, and, consequently, the cutter in.

The cutter-carriage swings on the main spi ndie as a pivot for the purpose, among others, of running out curved or sunken corners of moldings in stone. \Vhcn it is desired to re tain the carriage in any position, the bolts 1' maybe tightened up so as to bind the carriage to the segment (Z.

in order to more accurately and uniformly swing the carriage upon the spindle, we may wori noth the outer vertical edge ofthe segment d, as shown at a in Fig. 7, and provide a worm, c, on the carriage, which meshes with said. worm-toothed segment. The worm 22 is sn in arms 10, projecting from the carriage, and said worm may be conveniently operated by a crank or handle, :0. In such a construction the bolts 1', if employed at all will serve simply to connect the segment and carriage,

With this construction of stone-cutting de vice we are enabled to cut moldings in slabs of marble or stone away from the edges, and we are also enabled to out through such slabs and divide them neatly into any number of parts. Such a cutting apparatus, combined with the adjustable slab-holding mechanism set forth in the application No. 160,094, filed March 25, 1885, will produce a machine capable otperlbrming a very large variety of work, although it will be understood that we do not limit the application of our invention to that single style of machine.

\Vhat we claim is- 1. The main driving-spimlle, combined with a cutter-carriage pivoted thereto, and thereby adapted to rotate thereupon, and a guideway for such carriage, substantially as described.

2. A cutter-carriage :t'or stonemolding ma chines, pivoted to amain driving spindle so as to rotate about the same in a horizontal plane, a guideway for such carriage, a horizontal shaft supported in said carriage, and a cutter secured to said shalt and rotating; there with, and means to rotate said shall, substantially as described.

3. A main drivingspindle provided with a 25 bevel-gear at its lower end, a cutter-carriage pivoted to said spindle, a shaft supported by said carriage, a cutter secured to said shaft,

and a bevel-gear on said shaft driven from the our hands this 11th day of November, A. l).
